#Reverse Proxy a Solr Instance#
It’s encouraged that you secure your Solr instance by placing the application on a different file server and behind a firewall. That’s an issue if you are trying to consume data from the Solr instance leveraging AJAX techniques.
##Problem##
- The website and Apache Solr live on separate boxes.
- A firewall protecting Apache Solr plus the cross-domain issue does not expose the necessary end-point to consume via AJAX.
- Depending on your sys admin setups, Solr may not live on a fully qualified domain (ie. http://12.34.56.789:8983/solr/#/)
- An AJAX call to consume the Solr instance’s JSON/XML won’t work cross-domain.
##Solution##
- Reverse Proxy directive, mod_proxy – Apache HTTP Server.
- This allows for an endpoint that is visible to the browser and we can consume the JSON/XML that rests within the Solr instance.
